Right so I've never been to Hargrove specifically but shadow figures in old industrial buildings are genuinely one of the most documented recurring phenomena we have and the mill environment makes total sense - the combination of residual energy from decades of repetitive human labour, the acoustics, the particulate matter in the air affecting light, it all creates ideal conditions.
What I'd want to know is whether it had a defined humanoid shape or more of a mass. That distinction matters more than most people realise. A clearly defined figure with consistent proportions suggests something very different to the blob-type shadow anomalies you get from infrasound interference or environmental causes.
Did you have anyone else with you? Corroboration is everything here and I know that sounds cold but its the only way to rule out ocular fatigue from low light conditions. If you've got photos or video even partial footage post it up, this community has some decent eyes for picking apart whether something warrants further investigation.
